Question

It’s absolutely strange, but I can’t find any Java/Android URL parser that will be compatible to return full list of parameters.

I’ve found java.net.URL and android.net.Uri but they are can’t return parameters collection.

I want to pass url string, e.g.

String url = "http://s3.amazonaws.com/?AWSAccessKeyId=123&Policy=456&Signature=789&key=asdasd&Content-Type=text/plain&acl=public-read&success_action_status=201";

SomeBestUrlParser parser = new SomeBestUrlParser(url);
String[] parameters = parser.getParameterNames();
// should prints array with following elements
// AWSAccessKeyId, Policy, Signature, key, Content-Type, acl, success_action_status

Does anyone know ready solution?

Answer 1

There is way to get collection of all parameter names.

String url = "http://domain.com/page?parameter1=value1&parameter2=value2";
List<NameValuePair> parameters = URLEncodedUtils.parse(new URI(url));
for (NameValuePair p : parameters) {
    System.out.println(p.getName());
    System.out.println(p.getValue());
}
